Water pumps for domestic water supply: advice on choice and feedback

Residents of high-rise buildings do not think about buying water pumps, pressure stations and other equipment. All this is not necessary, since the water comes from the central water supply. But here's what to do to the private sector, where you often have to settle for a well or a well. Usually the matter ends with the design of an autonomous water supply. One of the most important parts is the choice of equipment. Let's talk about how to select water pumps for domestic water supply and what to do with it.

General information

Autonomous water supply is a complex system, which consists of a large number of elements. The key component is the pump. And their types, as well as models, there is a huge amount. These are surface and deep pumps of domestic and European production. Of course, such equipment effectively works only in a complex. Therefore, you have to buy a hydraulic accumulator, automatics, etc.

The principle of the pump is that it sucks water from a source, whether it's a well or a well, and supplies it to the consumer. Usually not directly, but first in the tank. As noted above, today there are a variety of water pumps for domestic water supply. Between them, they differ in their technical characteristics and dimensions. It is extremely important to be able to choose the right equipment. For this, it is necessary to be guided by a number of requirements, which we, in fact, will talk about.

On the head and water supply

When it comes to time to go to the store and buy a pump, we immediately begin to determine the technical characteristics. But it is advisable to do this before you go for the equipment. There are a number of pump characteristics that play a big role. It is impossible not to mention, for example, the supply of water. This characteristic is responsible for performance. That is how much the pump can surpass the water in a period of time. Currently, there are models available on the market that provide 1.5-9 m ³ / hour. But you must choose the pump based on your own needs. Count how much water you spend per hour.

Next is to decide on the pressure. This characteristic indicates how far the pump can be fed by the carrier. Usually this parameter is indicated in meters. In principle, the closer the source of water to your home, the better. However, it is undesirable to place the well too close to the foundation of the building. In any case, the head is lost due to the branching of pipes, resistance, and also the supply of media to the upper floors. Therefore, it is necessary to take a small stock here. Water pumps for domestic water supply have a technical passport, where the head is indicated.

Which water pump for domestic water supply should I choose?

Here we have very little choice. But in fact, there is none at all. The fact is that there are deep and surface pumps. The first are ideal for a well of shallow depth, usually less than 10 meters. They are not submerged in water, but are installed on a special platform, or caisson. Deep models are suitable for wells and wells with a depth of more than 10 meters.

Any of the above types of pumps can be centrifugal or vortex. In this case, both of them have their own advantages and disadvantages. More important is how the equipment is managed. It is best to give preference to automatic models, rather than manual, as they are more convenient and practical.

Surface and submersible pumps

The surface pump is mounted on the surface of the well. A pipe is connected to the equipment, which is lowered to the bottom of the well and pumped out with water. The key features of this pump are that you can install it yourself, just like you can maintain it. But usually the performance of such a pump is not too big, and even during operation it rustles. Although hardly the latter can be considered a serious drawback. The limiting factor is that there is one more minus - cooling. If the submersible pumps are cooled by water from the well, in our case the fan is responsible for this.

Submersible pumps are divided into deep and ordinary pumps. The second descend to a depth of 10 meters, and the first - to 10 meters or more. Currently, you can find models that can work at a depth of 30 meters, but you hardly need such a device. So, the advantages of submersible pumps are that they are efficient, do not have cooling problems and do not freeze in the cold season. Repair and maintenance is difficult, but given the low frequency of such work, this is not a significant disadvantage.

Centrifugal and vibratory

The centrifugal water pump for domestic water supply in comparison with the vortex has several significant advantages. Of course, here the scheme of pressure is fundamentally different. We have a wheel with blades (like a fan) on the shaft. It creates a vacuum in the shaft region. The pressure zone is at the ends of the blades. So, centrifugal pumps are very productive, and they differ from vibrating ones. Performance is limited by the power of the electric motor. In addition, such equipment does not tolerate various water pollution, so you need to put a filter on the input, which will increase the resistance and reduce the performance.

But vibration units can work with sealed water without any filter elements. But the vibration emanating from the equipment results in siltation of the source, which is not good. In the end, the performance of such pumps is less than the vortex (centrifugal).

Automatic or manual?

It is extremely important to understand that there are pumps that can work for a long time without any human involvement. This, as you have probably already guessed, we are talking about automatic pumps. They have a large number of sensors: protection against overheating, dry running, liquid level, etc. When a threat occurs, the equipment is turned off.

It is quite another matter - manual water pumps for domestic water supply. Repair of such equipment, as practice shows, is required much more often. For this simple reason, automatic pumps are more suitable for domestic water pipes. Let them be a little more expensive, but, believe me, soon it will pay off with interest.

Water pumps for household water supply "Grundfos"

There is hardly anyone who has not heard about Grundfos pumps. Today, it is one of the leading manufacturers of such equipment. What can we say, there are various models (submersible and surface), and types (vortex and vibration). All this allows the consumer to choose a pump that will be ideal for him. In addition, all equipment is equipped with overheating sensors, dry running. This manufacturer offers a huge choice in terms of technical characteristics of the equipment. You can find both low-power pumps for shallow wells and powerful models for downhole mines. It is impossible not to mention the high quality of the equipment. Here we mean both the resource of work, as well as the quality of the assembly as a whole.

What do consumers say?

You already know almost everything about how to properly choose water pumps for domestic water. Comments by consumers, by the way, play not the last role. The fact is that all manufacturers say about the high quality of their products, which, in fact, is correct, but not all pumps deserve attention. Someone has a sad experience of such purchases. With you can share them, and absolutely free. It is worth noting that you will already know for sure that it is better not to buy Chinese models. For example, many consumers note that with the technique of "VILO" from the leading European manufacturer there are no problems. While SAER pumps are sometimes repaired by the customer service for a very long time. In general, it is advised to give priority to mid-level equipment. It is of a very high quality, and it is not a problem to find spare parts if necessary.

Overview of the domestic market

Of course, one can not help saying that there are good Russian pumps. For example, Zubr ZNVP-300-25, also known as Rodnichok, is ideal for shallow wells (up to 5 meters). This pump vibrating type produces 1,400 liters per hour with a head of 55 meters. This is quite enough to supply water for both household and household needs. But you need to understand that vibrations can lead to siltation of the source.

Another example of a good domestic pump - "Caliber NVT-210/16". It is the same type as the previous one, but already somewhat less efficient - 700 liters per hour. Nevertheless, its power is only 0.2 kW, which is very small. At the same time, the price of such equipment is only 1,100 rubles. An excellent way out, especially if you have a well not more than 10 meters deep.

Kercher and Vilo pumps

The equipment of the German company "Kerher" is appreciated all over the world. These are excellent pumps, are very high quality and durable. In principle, this is not surprising, since the cost of such equipment is very high. For example, the model SPP 33 Inox 1.645-409 with a capacity of 6,000 liters per hour will cost 13,000 rubles.

But water pumps for domestic water supply "Vylo" - this is exactly what most of us need. The price is slightly lower than that of German technology. But something bad to say about them just does not turn the language. The excellent quality is also said by consumers who leave positive feedback on the forums and the manufacturer's website.

Conclusion

Here we are with you and talked about how to choose a pump for domestic water. Pay attention to the above characteristics. In particular, this is the head, the power of the equipment and its type. All this will help you make the right choice. As for the manufacturer, it is best to give preference to domestic companies. The reason is that repairing such equipment is much cheaper and faster than the European one. And there are no special comments on quality here. Much depends also on how correctly the equipment will be installed and how it will be operated and serviced in the future. In general, it's all on this topic.
